I recently installed Fedora 16 on a Dell VOSTRO 1510. I am quite happy with it, but I am concerned with the slow boot load time. I measured from launching the OS with GRUB till GDM, a boot load time of 1:01.42, which I experience as slow (that's subjective, my bad: I have not measured other boot times in prior Ubuntu installations, but I remember it to be half that time).

Pressing F2 during boot prints out various details. I notice the boot load is taking much time in the following phase:

What is LSB, ISCSI? Is one minute indeed a long boot time? Can I somehow improve the boot load time?

Here is my bootchart for more details:

Edit: thanks to some more documentation suggested by @vasquez, I have been able to remove some services and reduce boot time using systemd-analyze and systemctl. There are still more services however, which I may need to remove,see below. But how to know what services is doing what and gauge whether I need it or not?

Now the fedora-storage-init.service is taking the most time and removing it only replaces it by fedora-storage-init-late.service. What is this service exactly doing and how it can be sped up is yet a mystery.

Look inside /var/log/boot.log for more info on whats happening at boot time. Maybe you are starting daemons that that fail after a given time (network daemon?). One minute is a bit long.

@hesse: the log does not give me more information than F2 did.

Remove any wireless interfaces. It goes through the wireless interfaces and try to connect to each one, scanning for the AP each time until it times out. See if that makes a difference.

If you boot with "log_buf_len=1M systemd.log_level=debug systemd.log_target=kmsg" a lot more information will be available to you to examine

here is an old but interesting article on quantifying/reducing startup time, I don't know how much you can apply to the current fedora. LSB is the Linux Standard Base
